Only thing I can think of is some library you are using is overriding
BigDecimal#to_s. Can you try:
BigDecimal.instance_method(:to_s).source_location
Or if you want to monkey patch the literal_big_decimal method:
v.method(:to_s).source_location
If it gives you nil, it means the method was defined in C, which probably
means the stdlib version (unlikely that a C extension would override it,
but still possible).
Thanks,
